Method for processing American ginseng black ginseng by taking fresh American ginseng as raw material

Abstract

The invention relates to the field of American ginseng processing, and discloses a method for processing black ginseng by taking fresh American ginseng as a raw material. The method comprises the following steps that 1, the fresh American ginseng is washed to be clean, and then skin moisture is drained; 2, the American ginseng is placed in a steamer and heated to be 98-100 DEG C; 3, the temperature of the steamer is kept at 98-100 DEG C, and steaming is conduced for 56-60 h; 4, a steam source is cut off, and when the temperature in the steamer is lowered to 50-60 DEG C, the steamer is opened;5, the steamed American ginseng is cooled and then put in a drying room of 50-55 DEG C to be dried until the moisture content is smaller than or equal to 12%, the dried American ginseng is taken out,and a finished product is obtained. By adopting the processing technology, the content of ginseng rare saponins such as the ginseng monomer saponin Rg3 and the ginseng monomer saponin Rg5 in the American ginseng can be increased to the maximum extent, various original ginseng monomer saponins of the raw material fresh American ginseng are converted into ginseng rare monomer saponins to the maximumextent, and the rare glycosides can be kept not continue to hydrolyze. The effective ingredients ginseng saponin Rg3 and ginseng saponin Rg5 of the American ginseng black ginseng are greatly increased compared with those of the traditional process, the technology is stable, the processing efficiency is high, and the effect is significant.

Description

technical field [0001] The invention relates to the field of American ginseng processing, that is, a method for processing American ginseng black ginseng by using fresh American ginseng as a raw material. Background technique [0002] In the prior art, black ginseng is a new variety in the ginseng processing industry. Black ginseng products contain active substances that improve human immunity, such as ginsenoside Rg3 and ginsenoside Rg5, which are superior to Sun-dried ginseng and red ginseng. Fresh American ginseng does not contain rare ginsenosides such as ginsenoside Rg3 and ginsenoside Rg5, which are produced through the Maillard reaction (heating reaction) during the processing of black ginseng. However, due to the different processing techniques of black ginseng, the content of rare glycosides such as ginsenoside Rg3 and ginsenoside Rg5 in black ginseng products is uneven. The content of ginsenoside Rg3 in existing commercially available black ginseng products is sho...

AI Technical Summary

Problems solved by technology

[0007] 1. The steaming temperature changes sharply from high to low, the temperature difference span is large, the drying temperature is too low, the steaming temperature is too low and close to the drying temperature, and the temperature is too low. After the temperature is increased, the temperature is in the state of saturated steam and pressure, and the quality of the product is difficult to be consistent;

[0008] 2. The steaming temperature of some processes is under high pressure, and the steaming time is long. Fresh ginseng is easily broken, which affects the appearance and quality of black ginseng products.

[0009] 3. Repeatedly increasing the drying process in the traditional process, the process is cumbersome and difficult to operate, which is not conducive to large-scale production; part of the product process of ultrasonic treatment and the method of adding biological enzymes for black cucumber processing, the steaming temperature varies greatly, and the product quality is consistent The nature is difficult to grasp, the active ingredients of the product in the ultrasonic treatment stage or after the addition of biological enzymes are basically lost to the water medium or the ultrasonic effect is difficult to play, and the operation is complicated

Or, because the steaming temperature is too high, ginseng monomeric saponins are excessively hydrolyzed, the content of rare saponins such as ginseng monomeric saponins Rg3, Rg5 and overall saponins is too low, and the product quality is poor
